Announcements

In General
Be respectful! There's another person on the other end of that conversation! The forums are a place to discuss anything related to Overwolf and beyond but want this to be a place where people feel comfortable to participate and have fun!
Keep it on topic, keep it constructive - Threads should be constructive and have a clear topic. Replies to that topic should be relevant. Bumping a thread without adding relevant information is not considered constructive. Bumping a thread from a long time ago is also not constructive (Overwolf updates every 2 weeks, things change).
Attacks or Accusations are not acceptable - Attacking another person is unacceptable, the circumstances are irrelevant, just don't do it.
Read the topic - Know what people are talking about in the thread. Stick to the given topic and don't derail it.
Search - We have a great search function, use it before you post a new thread as it's possible someone has asked your question before and there's info on it. Don't see something about your question or topic after searching? Post it! (keep in mind that bumping threads from a long time ago is not recommended, post your own).
Don't post about locked or deleted topics; they were deleted for a reason.
No petitions, demands or "When will.." We have places for asking for games, features and we will tell you when something is coming. We don't give dates for a reason.
Don't try getting around the swear filter, it's not cute or funny.
This is not a place to break NDA's, talk about something illegal or break any law from any country. We will contact the necessary parties involved and you will be pursued to the extent of the law.
No spam. You will be banned and your post deleted.
Please write in English. This is an international forum and we'd like everyone to be able to participate.
Bad Behavior
Insults, racial slurs, profanity, vulgarity.
Trolling - You know who you are, and we will find you.
Nudity, porn or anything obscene.
Flaming - We don't have a trained fireman on staff, so don't do it.
No advertising - No one wants to buy that shirt off of you, or that WoW gold.
No insulting any religion (fake, real, or imagined), sexual orientation, gender or culture.
No talking about drugs or performing illegal activities.
Impersonation - Don't do it, people find out and you end up looking stupid.
What will we do if you break a rule?
Warnings - You get only one.
Thread/Post deletion - We delete your thread/post from the forums.
Suspension - Temporary forum ban.
Account termination - Permanent forum ban.
Legal action or report violations to the appropriate legal authorities.

Hello devs!

You will be able to discuss about code and product with other developers, in addition to other Overwolf team members that will be able to help you.
To get your invitation, please send us your email over this page.
See you there!

As I wrote in the original answer, not all the apps are eligible for the reward program. And also, we mentioned in the challenge website how developing an app is not a waste of time, as you can monetize your app. But it's definitely up to you what you do with your app and how you develop and improve it. From the challenge website:
MONETIZING YOUR APP TO HELP SUPPORT ITS FUTURE (AND YOURS!)
Some Overwolf apps already make thousands of dollars a month from advertising. Apart from creating something wonderful that will enhance the experience of millions of players, you could also make a living for yourself. Take a look at LoLwiz as an example - it became the full time job of its developers.

Hey there! welcome
You are allowed to use your website database to power up your app.
This Logitech Emulator that will help you develop the app without an LED keyboard. You can download it from here. You will find the "Developer" Tab in the Settings with access to the Arx Console, LCD Emulator, and LED Emulator.
If you submit your app to the LoL developers challenge you can't enter the reward program as well. And to be eligible to the reward program, we need to approve your full proposal first. Not all the apps automatically verified for the reward.
I hope those answers help you
